Keisei Narita Sky Acces Express

Hi, I found a transfer via Hyperdia from Narita Airport Terminal 1. I am planning to take the Keisei Narita Sky Acces Express at 12:04 (not today). I just donLt understand if I have to stay in the train at OATO and OSHIAGE thru to DAIMON (A09)? I am sure I have to transfer there to reach my final destination KACHIDOKI(E17). This only costs 1280 yen and is quit fast. 85 minutes. At the top of the route there stands just 1 transfer but they mention different trains? I donLunderstand.Can you help me? Thxs in advance. Josephina

It is route 4. May 14, 2014, cheap route 1280 yen.

Some trains run right through without having to change. Look for this sign, or if the sign says Nishi Magome it's OK. Or ask the attendant before getting on the train. Just say "DAIMON?"
